COVER FOR CONVEYERS AND GLAMPING MEANS THEREFOR Filed Jan. 29, 1955 2 Sheets-Sheet 2 IE4? I ATTORN% l NVENTOR [q'gar fiewafar VIII/ ill! nu-n Patented Apr. 21, 1936 UNITED STATES PATENT OFFICE COVER FOR CONVEYERS AND CLAMPING MEANS THEREFOR The present invention relates generally to covers for conveyers that handle coal or other material, and has for its main object and feature the providing of a sectionalized cover of simple and inexpensive construction but sufficiently sturdy towithstand the somewhat rough treatment to which devices of this character are subjected, also a cover that can be easily applied to the conveyer and in which the feed-end section can be readily removed for the purpose of gaining access to the lower or feed end of the conveyor to thereby admit of the removal of any remaining material at the said lower end of said conveyer.

In the accompanying drawings the invention is disclosed in several concrete and preferred forms in which Fig. l is a perspective view of one form of a conveyer showing all the sections of the cover in position with the exception of the lower or feedend section;

26 indicates a conveyor typical of those employed in handling coal or other material, said conveyer being supported on a framework 2| that is maintained in a tilted position by means of wheels 22. The framework of the conveyor is provided with upstanding side cheeks of one kind or another. Usually the side cheeks that extend through the major length of the conveyor are called skirt-plates, here designated by 23, but at the bottom end of the conveyer there are generally provided other side cheeks, spaced somewhat farther apart than the skirt-plates, and said other side cheeks are usually referred to as conveyer feed-end plates, and are here designated by 24.

In the instant exemplification of the invention, the cover consists of six sections, here indicated by A, B, C, D, E and F, and of these C, D, E and F may be and preferably are of the same construction, whereas sections A and B are somewhat modified with respect to the other sections, for reasons which will presently appear.

All of the sections are dome-shaped, in this instance substantially semi-cylindrical. Section A is preferably provided with two bands or stops 25 and 26 located some distance from the ends of the section, and is somewhat shorter than the length of feed-end plates 24. The middle portion 21 (Fig. 3) of section A is preferably provided at its edges with strengthening beads 28 and. inturned flanges 29, which latter are adapted to rest ontop of feed-end'plates 24 that constitute upright side cheeks. The upper portion 35 (Fig. 4) of section A is devoid of internal flanges but preferably has cut-out portions 3!, to facilitate its insertion in section B, and a strengthening bead 32. The lower portion 33 (Fig. 5) of section A is preferably provided with outturned flanges 34, which also constitute strengthening beads, and which overlie abutment member 35 carried by the frame at the extreme lower or feed-end of the conveyor. When section A is placed in position (the other parts being already in posi",

end plates and the skirt-plates, consists of a 2 lower portion 31 (Fig. 6) and an upper portion 38 (Fig. '7), these two portions being defined by slit 39. Lower portion 31 is wide enough to extend between the relatively widely separated feed-end plates and is preferably provided with strengthening beads 40 but is devoid of any inturned supporting flange; upper portion 38 extends between the skirt-plates and is provided both with strengthening beads 4| and with inturned flanges 42 the latter resting on top of the skirt-plates. Sections A, C, D, E and F can conveniently be of standard length, but section B will preferably vary in length depending on the dimensions of the conveyor frame, and slit 39 will be so positioned that the lower portion of section B can be fitted to span the feed-end plates, whilst the upper portion can be fitted to span the skirt-plates. Clamping means G is preferably associated with the lower portion of section B at each side thereof and will be more fully described later on, suffice it to say here that bolt g which connects the two members of each clamping means, rests directly on top of, or extends over, the side cheeks formed by the feed-end plates. The upper portion of section B also has a cutaway portion 42 so as to facilitate its introduction into section C.

Sections C, D, E and F are all constructed alike (Fig. 8) and are provided with strengthening beads 43 and inturned flanges 44, the latter resting on top of the upstanding cheeks formed by the skirt-plates. Each of these sections is provided at each side with a clamping means G, the

bolts 9 of which rest directly on top of, or extend over, inturned flange 44. Each of said sections C, D and E have cut-out portions 45 at their upper ends to facilitate the introduction of each section into the next higher one. Section F need not have these cut-out portions and may, by preference, extend beyond the end of the conveyer. Preferably also, section F has two sets of clamps G on each side.

Each clamping means G consists here of two opposed clamping members G and G connected by a bolt 9 having a tightening nut The inner opposed faces of the two clamping members are peculiarly constructed, lower faces G and upper faces G being disposed at an angle to each other so that the lower faces may clamp the upstanding cheek of the conveyer frame, and the upper faces may clamp the angular or curved dome of the cover. Bolt g is located substantial- 1y at the point of junction of faces G and G It will be seen from this construction that no holes need be drilled in the conveyer end plates or in the skirt-plates, the clamping members engaging the side cheeks, or the side cheek and the beaded portion, if any, of a cover section, bolt g passing through the cover section but extending over the side cheeks. This makes for quick assembling, and after the parts have been placed in position and bolt and nut g and g are tightened, the clamping members will not only clamp the cover section to the conveyer frame but will also clamp the cover section itself thereby tending to stabilize the latter.

In assembling the parts, cover section F will first be placed in position and secured to the conveyer frame, and'thereafter each succeeding section will be applied as will be obvious.

In Fig. 9 is shown a modification in which a cover section X is shown devoid both of strengthening beads and inturned flanges. In Fig. 10 is shown another modification in which cover section X is, in addition to the strengthening bead and the inturned flange, provided with a depending portion 46.

In Fig. 11 is shown a modification in which two adjacent cover sections X and X have cutaway portions 41 at both ends, the clamp G having faces'large enough to engage the cover sections beyond said cut-away portions.

In Fig. 12, the upstanding cheek 48 of the conveyer frame is provided with an outboard flange 49, and cover section X is provided with an outturned flange 55, which also forms a strengthening bead, that rests on outboard flange 49, and with a turned-down portion The clamping means G is here modified slightly as shown to accommodate members 49 and 50.

In Fig. 13, the upstanding cheek 52 is provided with a horizontal ledge 53 and cover section X is provided with a strengthening bead 54 that rests on 53, and with a dependent portion 55. Clamping means G here used have horizontal jaws and an adjustable bolt 56 to clamp 53 and 54 together.

I claim:

1. The combination with a conveyer frame having spaced apart skirt-plates, and also conveyer feed-end plates spaced somewhat more widely apart than the skirt-plates, of a removable cover section of less length than the length of the feed-end plates, abutment means on the frame to prevent endwise displacement of said section, a second cover section extending both over the feed-end plates and over the skirt-plates and fitted to both of these plates, means to clamp said second section to the frame, and a plurality of cover sections fitted to the skirtplates and clamped thereto.

2. The combination with a conveyer frame having side checks, of a dome-shaped cover section of sheet material, a two-part clamp to clamp the cover section to the side cheeks and to clamp opposed faces of the cover section to thereby stabilize the latter, and a bolt connecting the two parts of the clamp and extending over the top of the side cheeks.

3. The combination with a conveyer frame having side cheeks, of a cover section of sheet material, clamping means that come on opposite sides of an imperforate portion of the side checks to clamp the edges of the cover section to said side cheeks, and a bolt passing through said clamping means and extending over the top of said side cheeks.

4. The combination with a conveyer frame having side cheeks, of a cover section of sheet material, clamping means that come on opposite sides of an imperforate portion of the side cheeks to clamp the edges of the cover section to said side cheeks, and a bolt passing through said cover section and clamping means and extending over the top of said side cheeks.

5. The combination with a conveyer frame having side cheeks, of a dome-shaped cover section of sheet material having inturned supporting flanges resting on top of said side cheeks, a twopart clamp to clamp the cover section to the side cheeks and to clamp opposed faces .of the cover section to thereby stabilize the latter, and a bolt connecting the two parts of the clamp and extending over the top of the supporting flange.
